- Larger and heavier form factor
- Gaming-focused design may not appeal to all users
- Camera likely not a primary strength
Display Comparison
The Asus ROG Phone II boasts a measured peak brightness of 626 nits, offering excellent visibility in bright conditions. While the Aquos Zero 2’s display specifications are not provided, Sharp historically focuses on color accuracy and viewing angles. The ROG Phone II’s infinite (nominal) contrast ratio suggests a strong OLED panel, crucial for immersive gaming. The absence of LTPO technology in either device means refresh rate scaling isn’t as power efficient as newer panels, but the ROG Phone II’s larger screen size is a significant factor for gaming and media consumption.
Camera Comparison
Both phones feature photo and video capabilities, but detailed camera specifications are limited. Without sensor size or aperture information, a direct comparison is difficult. However, the ROG Phone II’s focus on gaming suggests camera performance was not a primary design goal. The Aquos Zero 2, as a flagship, likely prioritizes image quality, but without specifics, it’s impossible to quantify the difference. The inclusion of a 2MP macro camera on many phones of this era is largely a marketing gimmick and unlikely to significantly impact image quality.
Performance
Both devices utilize the Qualcomm Snapdragon 855 series, but the ROG Phone II features the Snapdragon 855+, a slight but noticeable upgrade. The 855+ boasts a marginally higher clock speed (2.96 GHz vs 2.84 GHz on the Aquos Zero 2’s 855) on its prime core, translating to a small performance boost in CPU-intensive tasks. Both share the same Kryo 485 core architecture. However, the ROG Phone II’s superior thermal design, a hallmark of the ROG line, allows it to sustain peak performance for longer periods, mitigating throttling during extended gaming sessions. The lack of LPDDR5x specification for either device suggests they both utilize LPDDR4X, limiting memory bandwidth compared to newer standards.
Battery Life
The Asus ROG Phone II shines in battery endurance, achieving a remarkable 114-hour rating. This is coupled with 30W wired charging, QC4 support, and even 10W reverse wired charging. The Aquos Zero 2 utilizes PD2.0 charging, but its battery capacity is unknown. The ROG Phone II’s faster charging speeds significantly reduce downtime, a critical advantage for gamers. The 114-hour endurance rating suggests a large battery capacity, allowing for all-day use even with demanding applications.
Buying Guide
Buy the Sharp Aquos Zero 2 if you prioritize a lightweight, pocketable flagship experience and value a high-quality display in a more compact form factor. You'll sacrifice some raw performance and gaming-specific features. Buy the Asus ROG Phone II ZS660KL if you are a mobile gamer or power user who demands sustained performance, fast charging, and long battery life, and are willing to accept a larger, heavier device.
